How to determine which codec is missing when play back audio/video via Phonon?
If you know please help me. thanks in advance.
You can use isMimeTypeAvailable to check what Phonon is saying it's capable of decoding.

I have two AVI videos. one will play in an application i am using and the other will not.
looking at them in Media Player Classic properties, they have exactly the same specifications
Codec : DVSD
Named: DVC/DV
but looking at them in GSpot, I finally found a difference.
the working file uses OpenDML AVI 2.0
whereas the file that will not open uses AVI 1.0
I need to convert one to the other, but i cant find a way to convert from one codec to a different version of the same codec, muchless how to find different editions of the same codec.
If anyone has an idea of how to fix this or what the other differences may be, please let me know.
The application I am trying to open these with only functions on Windows XP if that is any indication of what the problem may be.
using the option "save as old avi format" in VirtualDub solves this problem.

As part of a project work i am supposed to "implement" any network protocol of my choice. I googled for it but didnt find anything that would help a beginner like me to start off. Could anyone please give some ideas on where to begin?
Thanks in advance!
PS: am not sure of the tags either.
You can try DHCP. It is relatively simple and common.

To start you can cover the same subnet/vlan case. (Server client same subnet.)
Next do the different subnet/vlan case if you have time.
Does anyone know of a sound library for IOS that has been ported to work with Air applications?
I was looking at his list: http://www.adobe.com/devnet/air/native-extensions-for-air.html and did not see anything related to sound but hoping I can find something out there thats not on the list.
Thanks
you can check this one: https://github.com/mateuszmackowiak/SoundExtension
This library enables you to control the default player (pause, play and others) and volume.

You can find the extensions here, if not available request one from 'em they will help.
Follow steps in this will be able to make your own pretty soon....

I would like to encode video in my app with VP8. I use RGB24 format in my app but VP8 DirectShow filter accepts only YUV format (http://www.webmproject.org/tools/#directshow_filters).
I've googled the "RGB to YUV directshow filter" but no success. I don't want to write this filter myself from scratch, so I would appreciate if you help me with the information on where to find such filter.
Thanks!
You could try Geraint Davies' YUV transform filter to see if it supports the conversion.
Starting from Vista you can use Color Converter DSP, does this help?
If you know how to implement a transform filter, I have a fast YUV to RGB algorithm somewhere. I used DirectShow a looong time ago, so I can't be of anymore help than this :P
